MMBZxxV Power Dual Surface-Mount Zener Diodes

Diodes Inc. MMBZxxV Dual Surface-Mount Zener Diodes are designed for applications requiring transient overvoltage protection capability. These devices have a 24W or 40W peak power dissipation (P_PK) rating at 1.0ms and a power dissipation (P_D) rating of 225mW. These are available in breakdown voltages (V_BR) of 5.6V to 33V (typical). The Diodes Inc. MMBZxxV unidirectional double ESD protection diodes come in a common cathode configuration. The device is designed for ESD and transient overvoltage protection of up to two signal lines.
